7x7x7 x 7 7 can be simplified to:
A 57
B 75
C 7x5
D 75
E 77 777​

Well first of you start off by multiplying 7x7x7 which is 343 and then you multiple 343x77 which is 2,401. That’s your answer overall! Now to simplify: it can’t be E. It can’t be A. And it can’t be C. So that leaves us with B and D. And both B and D are the same exact answer so guessing i would say !

Hope that helps have a good day and please consider brainliest!!
